Sutures and Wound Repair/ General Surgery (ABSA) Practice Test

The purpose of bumpers or guards on tension sutures is to prevent heavy suture material from cutting into the skin. These bumpers distribute the tension exerted by the suture over a larger area of tissue, thereby minimizing the risk of tissue damage and pressure necrosis. This is especially important in areas where the skin is thin or delicate, as excessive pressure can lead to complications such as ischemia or further tissue injury. By providing a protective barrier, bumpers help maintain the integrity of the skin and support the overall healing process. While the other options touch on aspects of wound care and suture usage, they do not directly address the primary function of bumpers in relation to tension sutures. For instance, while bumpers can indirectly support wound healing by reducing pressure and preventing tissue damage, their main role focuses on the mechanical action of protecting the skin from the suture itself. Similarly, while they do not specifically aid in suture removal or provide added strength to the suture, their design enhances the overall effectiveness and safety of suture placement in tension scenarios.
